McGeehans of Donegal, Ireland or near it

Looking for any information on Rose McGeehan of Donegal, Ireland. She was born November 8, 1901 - Glenties, Donegal, Ireland. She was the sister of Cornelius McGeehan and Patrick McGeehan. I know for sure that Cornelius and Rose came to the U.S, but not 100% about the others. Nothing is known about their parents.

Also, I know that there is a Philomena McGeehan, married to Noel Manley. But I don't know how Philomena and I are related.
